To all 'whom it muy concern Be it known that I, An'rnrnz J. neonatinAUr/r, a citizen ot' the United v'tates7 residing at Rogers Park, Chicago, in. the county ot' Cook and State of Illinois. have invented new and useful In'iprovernents in Plumbers Furnaces, of which the following is a speci- Iication.

This'in'vcntion relates to lumbers furnaces and it consists in the novel features hereinafter described and claimed.

An. object o't the invention is to provide a furnace ot the nature indicated especially adapted for plumbers uses,

In the accompanying drawing:-Figgjure l is a side elevation ot' the furnace with parts broken away and part in section. Fig. 2 is a horizontal sectional View ot the same cut on the line o'l Fig. l. Fig. 3 is a dctailed sectional View of a portion of the same. Fig. 4 is a plan View ol a coil used in the furnace. Figs. 5 and 6 are detailed side elevations of igniting elements used upon the furnace. Fig. 7 is a sectional View otl the valve used upon the furnace, the View being cut on the line 7-7 of Fig. 2. Fig. S is a sectional View oit 'the lower portion of a pump used in the furnace.

The 'furnace includes an outer tank l 'with in which is located, an inner tank 2. The outer tank l is provided with an opening 3 which is norniially closed by a plug ll and through this openingr liquid fuel or oil may he introduced .into the tank l. The tank 2 is provided with lan opening normally closed by a plug (S. The said opening may be employed for admitting liquid fuel into the inner tank 2. A passage way 7 connects the upper portion of the tanks l and 2 and is provided with a check valve 8 which when the air in the tank l arrives at a certain de gree o1 pressure opens under the said pres sure and permits the air to flow through the passage way into the. tank 2. This valve includes a ball attached to a spring.

The means t'or creating air pressure in the tank 'l will now be described.

A cylinder 9 is supported 'from the top of the tank l and opens at its outer end above the top of the said tank. The outer end ol the said cylinder is normally closed by a cap 10. A check valve 11 :is located at the lower end of the said cylinder 9 and controls the outlet of .the said cylinder and also prevents the oil 'trom the tank l from AflowingY up into the cylinder 9. A piston 12 is slidahly mounted in the cylinder i) and a stem t3 is connected with thepistonand passes through the center ot' the cap 10. The stem i3 is provided at its upper end with a knob Alll. A spring `is located uponthe stem 123 and when the piston i2 is drawn toward the cap l() the ends ofthe spring 15 bear against the said cap and piston and cushions the movement ot the piston toward the cap. Theretore it will, he seen that by opcratinfr the pump mechanism just described air pressure may he created in thc outer tank i. and when the said prcssurrI reaches a certain degree it may force the valve S open and pass through the passageway 7 into the inner tank 2.

Urn-ights 16 are mounted upon the top of the tank l and support at their upper end a plate 17. The said plate 17 is provided at its opposite edge portions with outstanding lugs 18 with wh" ,h may he detzuihably oon' 'nected the end portions ot a bail 119. The

plate 17 is provided upon its upper side With ribs 2() and a shield .21 normally rests upon the upper side of the said plate and is held in position thereon by means ot the ribs 20. The central portion oi. the plate 17 is open. A hood Q2 depends from the plate t7 and surrounds the central opening thereof. The said hood 22 is provided in its sides with suitable openings and the bottom ot the said hood is closed and a mat 23 of asbestos or other suitable material is located upon the bottoni of the said hood.

A pipe 2li; passes down through the top of the tank l and terminates at its lower end in the vicinity olC the bottom ols the said tank although the lower end ot the said pipe is spaced from the bottom oit the tank. Above the tank l the pipo fr is provided with aeontrolling valve 23 ot any suitable character. A JT-M .26 is connected with the upper end of the pipe Qdiand one of the branches of the h-Tmis closed by a plug` One end ol a coil connected with the other end ot the said --T-- and a scction 29 of wire cord or rope inserted in the end portion ot' the coil 25s'. This section may be placed in the coil, hy removing the plug 27 trom the JV-- E25 by removiiw the said' plug the T`- may be connected directly with a source of supply. The coil is it'ornied with a series ot oonvoluwhich approximately vertically l v positioned Within the the coil 28 which conl is between the upper i Jne seid series of convoluierniost convolution 30 o' the into e section 3l Which is "iger-e end which lies trans-- Weisser;T ser s the central openingoit the series or" con ions. From the seid section 3l the end. prrtion oiff the coil s. nds down exteriorl;T et the convolution 3U is provided et its lower end With an --l..- htting A. nipple 33 is connected with the kti tine; sind is provided in its upper side h an orice 3st which is epproxiinstely centrally positioned with relation to the conf volutions and the intermediate portion of the shaped section 3l.

il sleeve 35 is screw threaded upon the outer end of the nipple 33 and is provided .upon its periphery with spaced iisnges 3o. resp 37 is located between the flanges 3Q. shsft 38 is journaled in the sleeve 35 and the adjacent end portion ot theE nipple 3Sv 'and s stuiling box 39 of env approved. chen. ecter is mounted upon the seid sleeve end is adapted to establish e, tigl t joint between the sleeve end the, shaft. rl`he shaft 38 is provided st its outer portionuith e coil t() and the end portion oi the seid shett ei:- tends heel; to the outer portion ot' th: sleeve end is downwardly turned es et 'tions lisposed end centrztll hood l tions il end is provided VWith e pyrophoric element 4Q. rlhe turned end. el is located between the flanges 36 While the sparking element ll2 is held by the coil 40 resiliently against the resp 37. Therefore the shaft 38 is constrained against longitudinal movement but is :tree to be rotated. The inner portion olthe shaft `which lies in the nipple 33 is flattened es et i3 and this flattened portion is loceteddirectly below the orifice so 'that when the shaft is rotated the seid uttened portions edges will scrape the edges et' the orifice and keep the seine -free troni the-ziccninulution oi'i carbon or other obstructing materiel. The inner end of the shaft 38 is twisted as ut LM consequently when the turned end el of the shaft is sprung; 'from between the flanges 36 end the shaft is nioved longitudinally out of the nipple und sleeve the said twisted end will encounter env loose materiel such es carbon end so i'orth which hes been removed troni about the oriice dit und will drag the seine out ot the nipple und sleeve es the shaft is Withdrawn troni the seine.
